SPECIFICATION forming part of Letters Patent No. 701,303, dated J une 8,1902.

Application filed September 20,1901. Serial No. 75,843. (No model.)

,To all 'whom it r11/ay con/cern: l

Beit known that I, CHARLES W. CURRIER, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinventeda certain new and useful Improvement in Gas-Burners, of whichthe following is a specification. n

My invention relates to the improvement of gas-burners of that class inwhich a plurality of burner-supporting arms are made to radiate from acentral supply-head or valve-casing; and the objects of my invention areto provide an improved valve construction and` pilot-light whereby acomparatively small flame maybe maintained in position for lighting thevarious burners, to so construct and arrange my improved valve mechanismand pilot-light as to insure an increased iiame at the mouth of thepilot-burner tube when the main valve is operated to supply the gas tothe burneresupporting arms, and to reduce the pilot-light after theiiame has been communicated to the burners. These objects I accomplishin the manner illustrated in the accompanying drawings, in which- Figurelis a vertical section of myimproved gas-supply head on line oc to' ofFig. 2. Fig. 2 is a sectional view on line fJ y of Fig. l.

Similar numerals refer to similar parts throughout both views.

In carrying out my invention I employ a gas-supply head or mainvalve-casing l having an upper end socket 2, into which leads the lowerend of a vertical gas-supply pipe 3. From the lower end of the socket 2leads downward a central port 4, which communicates with a centralvalve-chamber 5. From this Valve chamber lead radially outward pipearms6, from which are adapted to extend upward burner-supporting arms 7,which may be surmounted by mantles 8 or other suitable burners. Leadingvertically through the lower portion of the valve-casing or head l isthe threaded stem portion of a needle-valve 9, the latter having asuitable enlargement IO on its lower end to facilitate the turning ofthe same. As indicated in the drawings, the upper and preferably conicalend of the valve 9 is adapted to close communication between the port 4Land the chamber 5. The upper portion of the valve-body 9 is providedwith a central vertical port or recess ll, the upper end of lwhich .isadapted to be made to communicate with the lower termination of the port4, as shown. Leading into the lower portion of the internal port ll fromthe threaded outer side ofthe valve 9 is a short transverse port l2.Leading into an internally-threaded socket 13, formed in the lowerportion and inner side of the head l, is a short horizontal pipe-arm 14,which at its outer end terminates in a vertical valve-casing head 143,the upper side of this casing-head receiving the lower end of a.vertical pilot-light tube l5, the communication between which and theinterior of the valve-casing 14: is regulated by a needle Valve 16.Leading from the end of the pipearm 14 through the casing l to theperiphery of the valve 9 is a horizontal port 17, the latter beingadapted to register with the port or opening l2.

Although in the drawings I have for the sake of clearness inillustration shown but one of the burner-supporting arms 7 and one ofthe burners 8, it is obvious that one of these burner-arms and burnersbeing supported from each of the pipe-arms G will result in thepilot-burner tube l5 being projected between two of said burners.

In the construction of my device the ports 12 and 17 are so located withreference to each other that when the valve 9 is in its innermost orclosed position said ports will be out of direct communication, the onlycommunication between the same being through the comparatively narrowgrooves 12a, formed by the threads on the periphery of the valve. Incase there is not, as ordinarily exists, sufficient play between theengaging threads the threads at this point may be slightly led toprovide a passage for the gas. The gas which enters the head l from thepipe 3 and passes through the ports 4i, ll, and 12 and thence throughthe threadedgrooves to the port 17, arm 14, and pilot-burner tube l5 issufficient to maintain a comparatively small fiame at the upper end ofsaid pilot-tube and between the burners When the Valve 9 is turned,however, to the position indicated in the drawings-'that is, so as toinclose the port 4L and establish communication between the latter andthe chamber 5 and admit the IOO gas to the burners 8-the ports 12 and 17are in the first part of the operation of thus turning on the gas to theburners made to register one With the other. During the registering ofthese two ports it is obvious that a greater flow of gas is attainedthrough the ports 11 and 17 to the pilot-burner tube 15, with the resultthat an increased flame is provided at the outer end of the latter,which Will serve to ignite the gas at the adjacent burners, the flamefrom these burners being communicated to the remaining burners. Theoperation of turning on the gas being continued, it is obvious that theports 12 and 17 are again thrown out of direct communication, and theioW ot' gas through said ports is sufficiently retarded to decrease theflame at the pilottube mouth.

From this construction and operation it will be readily understood thatimproved means are provided for maintaining a pilot or igniting flame indesirable proximity to the burners and that this flame is increased whenignition is desired. It Will also be seen that this operation ofregulating the ame or volume of gas at the outlets of both the burners 8and the pilot is controlled by one valve.

Having now fully described my invention,

what I claim, and desire to secure by Letters Patent, is"

In a gas-burner, the combination with a valve-casing; a gas-supply pipeleading down- Ward therein,said casing having formed therein an internalchamber and an inverted valveseat in the top of said chamber, and a portleading thereto; a vertically-arranged valve loosely mounted in thecasing and controlling the vertical port said valve having a port inline with the port of the casing and adapted to be in communicationtherewith; said casing being provided with a port at right angles to thevalves port; and burner-supporting arms radiating from the casing and incommunication with said chamber; of a pipe extending from the casing incommunication With its right-angled port; and a tube at right angles tothe said pipe having a valveseat in its end, and a vertically-adjustablevalve in the end of the pipe adapted to contact the seat in the tube andcontrol the fiow ot' gas through the tube.
